Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Combining this study's adult decline with prior adolescent increases yields a non-linear lifespan trajectory: increasing during adolescence, plateauing in early adulthood, and declining in older age. → Palmer E.C. 2014

q2 · i? · associational · r2
Cross-study synthesis combining this article's adult sample (18–84) with Weil et al.'s (2013) adolescent sample (11–18 and adults up to 41). The article states this "reveal[s] a non-linear relationship between age and perceptual metacognitive efficiency, increasing during adolescence, plateauing in early adulthood, and declining in older age".
"Our results, when combined with previous research in adolescents (Weil et al., 2013), reveal a non-linear relationship between age and perceptual metacognitive efficiency, increasing during adolescence, plateauing in early adulthood, and declining in older age."
Discussion¶
Related Claims¶
- The age-related decline in perceptual metacognitive efficiency reflects both rising d′ and falling meta-d′ — related
- Executive function does not explain the age-related decline in perceptual metacognitive efficiency — related
- Metacognitive ability increases with age during adolescence and plateaus in adulthood when task performance is held constant — related
- Metacognitive ability improves across adolescence, with a logarithmic age trajectory — related
- Perceptual metacognitive efficiency declines with age in healthy adults aged 18–84, even when task performance is controlled — a narrower finding that bears on this claim
- Age-achievement functions take an inverted-U shape, but the quality of contributions remains roughly constant with age, with lower productivity reflecting reduced quantity of output — related
- Learning ability does not decline with age in healthy older adults — related
- Adolescents showed significantly lower metacognitive ability compared to young adults — reports the opposite
- How People Learn II updates and extends the 2000 How People Learn report by synthesizing research on learning from birth through adulthood in formal and informal settings — related
- The adolescent improvement in metacognitive ability is independent of perceptual task performance, which was clamped and uncorrelated with age — related
